Frequently asked questions
Is ICL7662EBD+T obsolete or still active?
The ICL7662EBD+T is Active per the manufacturer's lifecycle status. No discontinuation or last-time-buy has been issued — it remains a current-production part suitable for new designs and ongoing BOM lines.
What are the alternatives to ICL7662EBD+T?
Pin-compatible alternatives within the same charge pump inverter family include the ICL7660 and ICL7662 variants in 14-SOIC. The key difference is the input voltage range — the ICL7662EBD+T accepts up to 20 V, while the ICL7660 is limited to 10 V. Verify your supply rail before substituting.
